By that, I mean things like pressing the button for the green man, or to open train doors, call lifts, being lifted up to post a letter, and so on? Do they enjoy that little bit of power of "making something happen"?
As children, my brother and I loved such things - in fact, we would fight over who got to open train doors: sliding ones were a bit of a novelty in the 1980s. I liked dialling numbers (on an actual telephone dial). My dad quipped that whenever he announced we were going to a museum, we always had the same question: "will there be buttons to press?".
